Doc Type: Release Note
Doc Text:
RC4 is now disabled by default in OpenJDK 6 and OpenJDK 7 Earlier _OpenJDK_ packages allowed the RC4 cryptographic algorithm to be used when making secure connections using Transport Layer Security (TLS). This algorithm is no longer secure, and it has been disabled in this release. To retain its use, it is necessary to revert to the earlier setting of the `jdk.tls.disabledAlgorithms` of `SSLv3, DH keySize < 768`. This can be done permanently in the `<java.home>/jre/lib/security/java.security` file or by adding the following line: jdk.tls.disabledAlgorithms=SSLv3, DH keySize < 768 to a new text file and passing the location of that file to Java on the command line using the `-Djava.security.properties=<path to file>` argument.

Clone of bug 1217132 for RHEL 7.

Hi Andrew,

This bug has been selected for inclusion in 7.3 Release Notes. Could you please add info to the Docs Text field, so that I can use it to formulate the release note?

Perhaps it could be lumped together with bug #1302383?

Thanks.
Comment 5 Andrew John Hughes 2016-04-12 12:16:44 EDT
Hi Robert,

Yes, that sounds like the right approach. We did the same for this pair of bugs in RHEL 6.8, and you should just be able to re-use the documentation text from bug #1217131 to cover both this and bug #1302383.
Comment 6 Robert Krátký 2016-04-12 12:44:02 EDT
Great, thanks, Andrew. I didn't notice the 6.8 bug.
